Geo 18.1 Build 5 : New Features

Geo 18.1 Build 5 : New Features - Safe

• Standard sets of units (SI, kN-m, kip-ft and kip-in) may be selected via the Units and Preferences dialog.
• So as to help users to ensure that they are running the latest software a new version checking system has been implemented. This compares each executable file installed locally with the set that Oasys identifies as being the 'current' version. (The comparison is carried out locally; no data is transmitted to Oasys.) Executables for which updates are available are highlighted. Updates may then be downloaded from the Program's Downloads page on the Internet. This system enables rapid delivery of bug fixes and, occasionally, minor enhancements.
• Graphical input has been revised and now includes:
  • switching between node and element selection (without having to change the view shown);
  • automatic switch between single and group selection;
  • setting restraints on mesh lines before generating;
  • graphical entry of seepage restraints; and
  • better graphical input of pressure loads.
• In the graphical output:
  • multi-graph plots on the same axis have been reinstated; and
  • an envelope plotting facility has been added to the graph plot view.

  [NCR 9]
• Non-symmetrical results obtained for tunnel problem with symmetrically placed springs.
  [NCR 10]
• Scaling problems for plotting the stresses, bending moments etc.. and re-run the analyses may cause slightly differing results from old version
